most likely no. especially if it is a 1 cylinder. just like a lawnmower, the camshaft is built into the same peice as the crankshaft. you can't advance or retard the timing. i am most certain that your problem is in your carberuator. It is probably dumping too much gas into the cylinder. when the piston comes up and makes compression, the spark plug ignites and causes combustion, the exhaust valve opens and closes quickly, but there is so much gas in the cylinder that when the intake valve opens again to let more fuel in, the fuel already in the cylinder is still combusting and causes a backfire on the intake side which also burns all the fuel back up to the carberuator in a quick flash and backfire. i bet the spark plug is either fouled out, or showing signs of overheating from getting too hot because of prolonged combustion. tune up time.

The engine backfiring at idle, and at slightly off idle speeds is indicative of a lean fuel/air mixture. Try enriching your fuel mixture.

There are several possibilities for this. The usual culprit is that the timing is off. Make sure all your plug wires are correct. 1-8-4-3-6-5-7-2 in a counter clockwise turn.
Why a 1979 Chevy 350 keeps back firing through the carburetor if the firing order is correct?
You are bad out of time, or maybe you have wired the wires in the wrong rotation. It should be clockwise rotation. Check to see if you have wired it correctly, also if you have removed the distributor and reinstalled it you may be out of time.
